DEVICE AND METHOD FOR DETERMINING REFERENCE VARIABLES FOR ADJUSTING THE LIGHT DISTRIBUTION OF A RIGHT HEADLAMP AND A LEFT HEADLAMP ON CURVED ROADS

The device has a control unit (C) for determining angles from respective information such that angles for a right headlight (Sr) and a left headlight (Sl) are selected by the control unit. An interface (I) connects the device with actuators for adapting light distributions of the headlights or parts of the headlights. A conversion unit (D) converts the selected angles into reference input signals. One of the angles is limited into a limited angle by the control unit when amount of deviation between the angles is larger than a maximum allowable deviation. Independent claims are also included for the following: (1) a method for determining reference variables for adaptation of light distribution a right headlight and a left headlight of a vehicle during driving along curves (2) a computer program comprising a set of instructions for performing a method for determining reference variables for adaptation of light distribution a right headlight and a left headlight of a vehicle during driving along curves (3) a computer program product comprising a set of instructions for performing a method for determining reference variables for adaptation of light distribution a right headlight and a left headlight of a vehicle during driving along curves.
